KNOCKDOWN BARREL.

Specification of Letters latent.

Patented Nov. 10, 1914-.

Application filed November 13, 1913. Serial No. 800,887.

To all whom it may concern Be it known that I, ALBERT J. BUHTZ, a'citizen of the United States, and resident of Seattle, King county,\Vashington, have invented certain new and useful Improvements inKnockdown Barrels, of which the following is a specification.

My invention relates to barrels and particularly to knock down barrels,or barrels so constructed that they may be disassembled for shippingwhen empty.

The object of my invention is toproduce an improved and more practicaltype of construction, whereby the barrels may be partially assembledinto segmen s which will nest for compactness of transportation andmaybe easily and cheaply as'sembledwhen they are to be used.

My invention comprises the novel parts and combinations of parts whichwill be described in the specification and defined in the claims. 7

In the accompanying drawings I have shown my invention in the form whichis now preferred by me.

Figure 1 IS an end view of a barrel con structed in accordance with mynvention,

the construction being that used where the head is to be removable andthe head being removed. Fig. 2 is an elevation and partial section of abarrel end. Fig. 3 shows in perspective one of the segmental bindingstrips used for the staves at the end where the head is to be removable.Fig. 4 is a perspective of a segmental binding strip as made for the endof the barrel where it is not required to remove the head. Fig. 5 shows,in perspective and nested as they would be for shipment, the three stavesegments which may be used to form'the body of the barrel shown in Figs.1 and 2. Fig. 6 shows the. removable head. Fig. 7 is a section of acorner of a barrel showing how the head is secured in place and thecorrugations by which the bindings are more securely held in the staves.Fig. 8 is a cross section of a stave binding before it is put in. place.

In my invention I assemble a number of staves so as to form a segment ofthe completed barrel. The size of these segments,

that is, the number which would be required to make a barrel, may besomewhat varied, but I consider the most practical number to be three,and have showna barrel having the staves previously assembled into threelike segments. The staves are supposed to be of wood and, in general, ofa standard type of construction. The staves 1 as Izhave herein shownthem, do not have chamfered chines, nor are they crozed to receive thehead.

A number of staves l, sufiicient to form a segment of the desired width,are secured to- 4 gether by sheet 7 metal bindings 2 and 3, placed atopposite ends, these being longitudinally curved to conform to thecurvature of the barrel. The binding pieces 2 and 3 are alike, exceptthat the pieces 2 are modified in one wa to permit ready insertion andremoval 0 the head 4 after the barrel has been completely assembled.Each piece 2 and 3,'is bent over the ends of the staves, so as to incasetheir ends. A section 20 extends from the outer end corner of the stavestoward the center; the section 21 extends over the ends of the stavesand the-section 22 extends alongthe inner surface of the staves to apoint substantially coincidentwiththe outer surface of the head, wherean inwardly projecting flange 28 is formed by bending the metal uponitself. Themetal then 0011-.

tinues toward the center of the barrel as a section 24: of a widthsubstantially equal to. the thickness of the head-4 and is then bentinvirdly to form a flange 26w'hichengages the inner surface of the head.v

in the binding strips used for both ends of the barrel, but the onewhich is placed at the end of the barrel which receives the removablehead, is modified by having sub-- stantially one-half of the length. ofthe fiange23 cut away. The portion cut awaymay be concentrated in onecut, as I'have shown in the drawings, or it may be divided intoseparatedparts. The head 4,- which is placed in this end of the barrel, has itsedge notched, or recessed to conform to the sections of the flange 23which remains. That is, the gaps 4C1 match the sectionsof the flangewhich remain and the projecting parts 40 match with the gaps in theflange. In in- I I The above constructions are found alike serting thehead the projections 40 are,

shaped to the required form. At this time the cross section would be asshown in Fig. 8. To securely bind the whole together, certain partsofthe binding piece preferably those which lie in the plane of the head,are crimped or corrugated, as shown at 25, the corrugations being ressedinto the wood. These corrugations siiould preferably be offset from thenormal plane of the plate, wholly at that side which is next the staves,as is shown in Fig. 7. These corrugations would thus be embedded in thestaves and would then appear as shown in Fig. 7 The barrel segments thusformed may be nested, as shown in Fig. 5, for convenient shipping, theheads and hoops being also bundled. When the barrel is to be assembled,the segments which form the complete barrel are brought together and thebottom head inserted between the flanges 23 and 25 and hoops placed uponthe barrel and driven tight. In Figs. 2 and 7 I have shown wire hoops 5,although any kind of hoops may be used.

By reason of the fact that the bindings employed to secure together thestaves of a segment are made of sheet metal which hugs closely to thesurface of the staves and by reason of their location at the ends of thestaves, or at the chines, where the barrel is of the least diameter,they do not interfere with the application or removal of hoops of any ofthe kinds most commonly used. By reason of the fact that they embrace orare folded about the chines and further because of the inwardlyprojecting, head-holding flanges, they have a sufficient transversedepth in the direction of the diameter of the completed barrel, to givethem such stiflness as will cause them to hold their shape under anyordinary handling conditions.

at I claim as my invention and desire to patent is:

1. In a barrel, in combination, staves, means permanently joining theends of a plurality of staves to form separable and distinct segments,said rreans being provided with head securing members, and means for toform separable and distinct segments, said bindings at one end of thebarrel having two inwardly projecting flanges separated lengthwise thebarrel to receive the barrel head therebetween, and means independent ofthe said bindings for securing a plurality of the segments together toform a barrel body.

4. As an article of manufacture, a barrel segment composed of aplurality of bilged staves having metal bindings fixedly secured overtheir chines, said bindings being provided with head holding means andhaving transverse stiffness which maintains the curvature of the segmentin conformity with that of the completed barrel.

5. In a barrel, in combination, staves, a sheet metal binding embracingthe ends of a plurality of staves to form a segment, said binding beingfolded to, form two inwardly projecting flanges adapted to receive thehead between them, the part of the metal connecting said flanges and thecorresponding part of the outside arm of the binding having inwardlyextendin projections embedded in the staves, and hoops securing aplurality of segments to form the barrel.

In testimony whereof I have hereunto aflixed my signature this 7th dayof November, 1913.
